Here is my follow up Shooting Field Test to my ASG STI Duty One Non-blowback Table Top Review. During this Field Test Shooting video review I not only shoot my Non-blowback STI Duty One version but I also compare it to the Blowback ASG STI Duty One to see if fps and accuracy are effected when adding Blowback to the equation? I shoot 5 rounds through my Chronograph with both guns to get an average fps and I also step back 30 feet and setup resting my hands on a sand bag and standing in the back for a fairly secure shooting stance. I did my standard 10 shot grouping for my accuracy test from 30 feet away.

Overall both guns performed similarly and as expected the Blowback did effect the fps but not as much as I expected it to? I was expecting the Non-blowback STI Duty One to be at least 50 fps faster but it was only around 20 or so. I am fairly certain since the fps os so close between the two guns, that you will get more shots form a CO2 out of the Non-blowback ASG STI Duty One since there is no CO2 being used to make the slide recoil back and forth. In the end the Non-blowback STI shot an average fps of 373 while the Blowback version shot an average fps of 356.

When it came to accuracy, both guns performed about the same getting about a 2 inch group from 30 feet back. The Blowback STI did spread the BB's out more from side to side perhaps because of the slide recoil while the Non-blowback ASG STI Duty One seemed to shoot Horizontally tighter.

Personally since both guns shoot almost as high of fps and both STI Duty One's seem to be about the same accuracy wise. Why not just go with the blowback version since you will be shooting in single action most of the time which allows for a faster and lighter trigger pull. The only real downside to the Blowback STI Duty One is perhaps a bit more CO2 usage but you can still expect to get around 100 shots per CO2 which is very good for a CO2 blowback pistol.

Trigger Pull: The trigger pull on the ASG STI Duty One 1911 Non Blowback is fairly light in both single and double action. Take-up is the same in both modes but when in single action mode most of the trigger pull has little to no resistance until you get to the break point near the end where the hammer is released.Accuracy: In an Earlier review I shot the Blowback version STI Duty One 1911 air gun at a target from 20 feet away in a free standing position, and it performed well getting a 1.5 to 2 inch grouping right in the center of the target. The rear sight is adjustable for windage which is always nice to have just in case you are shooting a bit to the left or right. For me there was no need to adjust the sights. My Chrony testing with an eight shot averaged result was 373 fps - very decent for a blowback pistol! It will be interesting to see how this Non Blowback version performs since there is more CO2 going to the BB and less gun movement without the Blowback operation.

Build Quality: ASG did a great job designing and making the STI Duty One 1911 Non Blowback BB gun, they didn't really compromise on anything other than going with a polymer frame! With that said all that important parts like the Slide, Slide Catch, Safety, Mag Release, Hammer, Barrel and Magazine are all metal. The fit and finish as with all the ASG air guns is very good!Realism: The ASG STI Duty One 1911 Non Blowback version is a close replica to the real steel STI 1911, the only real giveaway is the trigger design, as a true 1911 trigger is not your typical lever type. Even with the different type of trigger the STI Duty One is a very good replica complete with STI licensing and trademarks.Purchased From: The Replica Airguns Store.

Pros:

No Blowback action but does have a working slide and slide catch.

Adjustable rear sight for windage.

Shoots in both single and double action.

Good quality control, very well made, fit and finish is good.

Should have good power and accuracy like the blowback version, perhaps even a bit better.

May have even better CO2 usage than the already good blowback version.

Metal drop out magazine.

Good STI Replica.

Holds really well in the hand.

Cons:

Trigger is not true to the real steel 1911.

No working grip safety like a real 1911.

Polymer frame rather than a metal frame.

CO2 can be hard to get out.

Comments:In terms of comparing the Non Blowback version of the ASG STI Duty One 1911 to the Blowback version without actually shooting it, they are pretty much identical except for the double and single action trigger found on the Non Blowback version. Even the slide seems to work the same. The big difference will be when I shoot the Non Blowback ASG STI Duty One. Will it shoot with a lot more FPS and will the reduced slide movement give it more accuracy? I am assuming yes to both of these question but I guess we will all have to wait and see when I do my official Shooting Field Test Comparison...

This video is to give you a heads up on a few guns I will be reviewing shortly. Most of them are different version of guns I have already reviewed except for the Baby Desert Eagle which so far has eluded me :)

I was waiting for a magazine for my ASG STI Duty One 1911 to show up so I could finally do this "Head to Head" Field Test Shooting Review Video for the ASG STI Duty One versus the ASG CZ 75 P-07 Duty versus the ASG Bersa BP9cc. All of which are Blowback CO2 4.5mm Steel BB pistols.

This Shooting Field Test went fairly well and all guns performed as expected, I did have one slide lock back on a loaded magazine with my ASG STI Duty One 1911 and one failure to lock back on the last shot with my ASG Bersa BP9cc, but it did eventually lock back.

During the Chronograph 5 shot per pistol test I got fairly similar fps from all three guns with the STI Duty One getting the highest of 372 average fps, the Bersa BP9cc getting runner up with 353 average fps and the CZ 75 P-07 Duty trailing the field just a bit with a 346 average fps.

During the target portion of this Field Test Shooting Review from 30 feet back in a semi rested position, again the pistols shot fairly similarly with all of them getting pretty close to 2-3 inch groupings. I did have a double shot right after my slide lock back on the STI Duty One as I pressed the trigger twice, once when the slide was locked back and again when I released it, this chambered two BB's into the barrel making the gun shoot a bit low for that double shot. With that negative one against the STI Duty One 1911, I did however find it the most pleasing to shoot! It had the best blowback action and the smoothest trigger, plus I just like holding and sighting in 1911's :)

The CZ 75 P-07 had the next hardest blowback with the Bersa BP9cc coming in second in the trigger department. All of these CO2 blowback BB pistols should get somewhere around 100+ shots pre CO2 if you take your time a bit between reloading magazines.

We have been taking preorders on many of our ASG Airguns and Airsoft guns for our Canada Replica Airguns Store, we where expecting them to be back in stock right around the end of the month. The good news is we got them a bit early so we are now filling back orders and most of our ASG inventory is now showing as in stock and ready to ship!

So if you've been waiting for an ASG gun, make sure to grab yours now before we run out again...
